STOP-MOTION FOR LOOMSQ To all whom it may concern:

Be it known that I, CHARLES D. LANNING, a citizen of the United States, residing at Dorchester, inv the county of Suffolk and State of Massachusetts, have invented an Improvement in Stop-Motions for Looms,

of which'the following description, in con nectionwith the accompanying drawings, is a specification, like letters on the drawings representing like parts.

.This invention relates to stop motions which, while they may be of general ap plication, are primarily intended for application to a loom to stop the same upon the occurrence of a warp fault, and preferably through mechanical agencies.

It is customary to employ detectors or drops individually supported upon the warp threads of a loom,-so that upon the breakage of a thread or undue slackness thereof the detector or drop pertaining to that thread assumes an abnormal position and is impinged upon by a feeler, resulting in stoppage of the loom. Such detectors, as generally constructed are composed of a thin strip of metal, and since they have heretofore borne the full or substantially the full strain of the feeler consequent upon the release thereby of the stopping mechanism for the loom, they quickly become bent or otherwise injured.

So far as 1 am aware, I am the first to relieve the detectors of the strain of the feeler, transferring the same to an abutment, so thatthe strain consequent upon the stopping of the loom is not only not borne by the detectors but tends to be positively relieved by the action of the stopping mech vanism.

Other features of my invention will be more readily apparent upon a detailed description thereof.

lVhile my invention may be embodied in a great variety of mechanisms widely differing in structure and operation, I have, in order that the principles of the invention may be made clear,.set forth one embodiment thereof in the accompanying drawings, wherein Y Figure 1 isa side elevation of a portion of the loom frame showing my invention applied thereto, the feeler being represented as having just impinged upon an abnormally posit1oned detector.

Referring specifically'to that single type or embodiment of my invention herein selected for illustration, the frame ofxtheloom 1s lndicated at 1, it being of any suit v able type. I If desired, my invention may be applied to the character of loom disclosed in the patent to Coldwell andGildard, No. 690,686, though. it WillbB understood" that I am in no wise to be limited to any particular type or character of loom. of the loom are represented at 22and are supported in the loom frame in any desired manner to sustain in the usual manner the warp threads 3. Preferably between 'the leasing members, detectors herein shown as.

The leasing members drops 4 are mounted individually upon the warp threads. 7 While I am not'to be limited to the type of dropherein shown excepting when specifically so stated, preferably I employ an open drop asclearly represented,

asI have found in practice that it is pref- GIELblG'lJO position the drops after the warp drawing operation and after the threads are in the loom than to draw the warps through the drops. Furthermore an open drop is more'flexible and limber at its lower 5 end, and in the event-of the employment of an electrical stop made.

motion 'a' better contact is ed upon or straddles one of a pair of bars the path ofmovement of a feeler 6. He're-' tofore, feelers have beenemployedadapted to bereciprocated orvibrate'd in'a determined path, into which path the abnormally J 95 As clearly represented, thedrop is mount-K positioned drop moves, thereby checking or interrupting the movement of the feeler and through intermediate mechanism stopping the loom. So far as I am aware, in prior constructions the strain of stopping the loom has been borne by the drop although attempts have been .made to prevent deformation of the drop by lateral or other guides therefor.

One of the important objects of my invention is to remove from the abnormally positioned drop the strain of stopping the loom by transferring it from the drop to some suitable abutment. It is apparent that this may be accomplished by mechanisms widely varying in construction and operation but involving this fundamental idea. In practice, I have found the construction herein set forth to be efficient. If desired, a single feeler 6 may be employed to cooperate with two banks of drops as represented. WVhile the feeler may be mounted to move in any suitable manner toward and from the drops, herein I. have loosely mounted the same upon a rock shaft 7 suitably supported in the loom frame, providing such feeler with the downwardly extending por tion 8 and lateral wings 9-9. In order to rock the shaft 7, whereon, in this type of the invention, the feeler 6 is mounted, I may employ any suitable means herein shown as an actuator. 'rl erein for the purpose I employ an actuator 10 fast upon the rock shaft 7 and having a forked lower end 11 to receive between the members thereof a cam or eccentric 12 mounted upon shaft 13. In the present type of the invention, I employ the weft cam or a cam upon the shaft that operates the weft hammer. Inasmuch as this shaft usually rotates at half the speed of the main driving shaft, the rate of movement of the feeler and hence its momentum when it encounters an abnormally positioned drop or detector are much lessened, thus reducing liability of damage to such detector. lVhile the actuator and feeler may be operatively connected in any suit able manner, preferably I connect the same for relatively yielding and herein effect this bypivoting upon the actuator a pair of downwardly extending lever members 14:, which herein have a flat broadened face to receive between them a laterally extending head 15 formed upon the lower end of the member 8 of the feeler. As clearly apparent, the said head 15 projects beyond the plane of the member 8 to permit proper engagement therewith of the said faces upon the lever members 14:. The face of the actuator 10 between the adjacent edges of the lever members lt is provided with a stop 15, which when said lever members 14: are normally positioned, as in Fig. 1, engage both of said inner edges. Prefen ably a coiled or other spring 16 is employed to connect the lever members 14, thus nor mally maintaining them in parallel posi tion but permitting movement of either one of said levers with respect to the other and with respect to the actuator upon engagement of the feeler 6 with an indicating drop bar, as will be evident from a comparison of Figs. 1, Q and 3 with Fig. t. By reason of the reduced rate of speed of the feeler, the spring 16 may be of a delicate character. Whether the head of the feeler 6 be dis placed to the right or to the left upon coir tact of an indicating drop bar, one of the lever members 1 1 will be held. from movement relative to the actuator by reason of its engagement with the stop 15, and the other lever member 14% will be moved away from said stop, and thus expand the spring 16 as indicated in Fig. 4. Ihe spring 16 thus tends to restore the parts to their position with respect to the actuator that is shown in Figs. 1, 2 and 3.

As stated, if I employ a connection be tween the feeler and the actuator, it may be of any suitable type. In the present type of my invention, I employ an abutment or abutments operatively connected to and herein rigid with the feeler, which abutments are therefore, in this form of my invention, movable and in the normal op eration of the loom are confined to a certain inoperative position or to a path of movement that may be termed an inoperative path. Upon impingement of the feeler upon an abnormally positioned drop, however, an abutment of any suitable nature is rendered operative by any suitable connection and in the present instance, wherein the abutment is movable, by holding or positioning it in an operative position, so that itmay be im pinged upon by a member of any suitable character to effect the stoppage of the loom, while at the same time the abutment receives the full strain consequent upon such stopping movement.

While the abutment or abutments may be constructed in many different ways whether or not rigid with or carried by the feeler, herein I mount upon or form with the feeler 6 the lateral wings 9, which during the nor mal working of the loom traverse a determined inoperative path as indicated in Fig. 3. I-Ierein the abutments 9 extend laterally from the rock shaft 7, so that the strain received by either abutment is transferred immediately to the rock shaft 7.

Any suitable mechanism may be employed to be actuated and herein by the abnormal or operative positioning of an abutment to effect stoppage of the loom. Herein, I employ a movable member, though I am not to be restricted thereto save as expressly stated. While such movable member may be mounted and operated in any suitable manner, in the present type of the invention I employ a feeler actuated member 17, pivotally mounted at 18 upon the actuator 10 and operatively connected as'by means of a rod 19 with a knock-01f lever 20 (see Figs. 1 and l) pivotally mounted at 21 upon the loom frame and having two shouldered portions 22 and 23 at opposite sides of the pivot 21. My invention may be embodied in a feeler actuated member of any desired type or embodiment. Such member, however con structed, I herein also term a secondary feeler or bunter, inasmuch as it has this function with reference to an abutment of whatever type employed, it feeling to ascerr' tain whether an abutment is operatively positioned. If such member in its feeling action finds an operatively positioned abutment, stoppage of the loom results. In the normal working of the loom, each of said shoulders is adapted, as indicated in Fig. 1, to engage the shipper lever 24, which may be retained in the usual notch to be released to stop the loom. Viewing Figs. 1 and 4, it will be apparent that movement of the knock-0E lever 20 in either direction will serve to stop the loom.

Herein the upper end of the feeler actuated member 17 is forked, each member 2-1 and 25 of such forked portion having an inturned portion 26 and27 adapted, in the normal working of the parts, to partake of a movement in a fixed path and to a fixed extent. In accordance with this type of my invention, I vary the path of movement of the feeler actuated member 17 in order to effect the stoppageof the loom, and herein this is specifically accomplished by interposing in the normal path thereof an abutment 9 to terminate or shorten the stroke of said member interposed in its path. I may, however, employ any suitable actuator and vary the path of movement thereof in other ways as, for example, by normally impartingl thereto a minimum length of stroke, which, upon the occurrence of a warp fault, is lengthened to effect in any suitable manner the actuation of the stopping mechanism.

- Viewing Fig. 8, it will be apparent that in the normal. operation of the parts the path of movement of each abutment 9 is such that the path of movement of the feeler actuated member, 'bunter, or secondary feeler 17 is not altered or afiected thereby. When, however, the feeler 6 in its feeling movement meets an abnormally positioned drop as indicated in Fig. 2, its movement is interrupted, and the abutment 9 is lifted above or displaced from its normal path of movement, as indicated in Fig. 2, bringing it into the path of movement of one of the inturned ends 26 of the feeler actuated member or hunter 17. In Fig. 2, the feeler 6 is represented as having just engaged the abnormally positioned drop, thereby abnormally positioning an abutment 9, because of the continued movement .of the actuator 10, which further movement is notrpartaken of by the feeler 6. Upon the continued movethat indicated in Fig. 41, thereby impinging the inturned end 26 upon the corresponding abutment 9. During the normal operation of the parts, the feeler actuated member 17 has moved bodily with the actuatorlO and has rocked about the point of connection X of the rod 19-and such feeler actuated memher as a center. When, however, the portion 26 engages the corresponding abutment 9, as indicated in Fig. 4, the further movement of the upper end of the feeler actuated member 17 is interrupted. Since, however, the movement of the actuator 10 toward the right, viewing Fig. 1, continues, the point of rocking movement of the feeler actuated member 17 is transferred from its lower end to the portion 26 at its upper end, and accordingly bodily movement of the lower end ensues, and hence a movement of the rod 19 to the right viewing Fig. or in the direction of the arrow therein. The knock-off lever 20 is likewise moved to the right and the shoulder 23 releases the shipper lever 24: from its notch to stop the loom. It is apparent that if an abnormally positioned drop were engaged by the feeler 6 in its opposite stroke, the inturned portion 27 of the feeler actuated member 17 would in the same manner engage its abutment 9 to ef-.

feet a movement of the rod 19 to the left viewing Fig. l, whereby the loom would be stopped through engagement of thefshoulder 22 of the knock-off lever with the shipper lever 24.

I may form the abutments 99 and the inturned portions26 and 27 in any suitable manner to facilitate proper engagement of the parts. Herein I have represented each abutment 9 as concaved, and the parts 26 and 27 as convexed. If desired, this construction may be reversed or varied.

While in the manner indicated the strain of stopping the loom is borne by an abutment and the rock shaft from Whichthe abutment extends, preferably I so construct or proportion the parts that in the impingement of the feeler actuated member upon an abutment, the feeling portion of the feeler is removed from engagement with the abnormally positioned drop. Ihis result may also be accomplished in any desired manner in other types of my invention. In Fig. 4, I have indicated such operation of the parts in the present type of the invention. IVhile this result may be accomplished in any desired manner, herein I effect the same by making the radius of the path of movement rod 19 longer than the distance between such point of connection X with the rod 19, and the axis of the rock shaft 7. Thereby, either inturned portion 26 or 27 engages an abutment 9 with such a direction of movement as to force the abutment upwardly and hence to move the feeling portion of the feeler rearwardly or from the abnormally positioned drop. It is apparent that were the path of movement of the portion 26 or 27 such as to tend to move an abutment 9 downwardly, the feeling portion of the feeler would be retained in engagement with the abnormally positioned drop. In other types of my invention I may accomplish this result in other ways as will be readily apparent to those skilled in the art.

I desire it to be understood that my invention may be embodied in mechanisms differing widely from that illustrated which is selected merely as an effective means for accomplishing the results that are to be secured.
